Answer:
x = 11
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
sum the 3 angles and equate to 180
5x + 4 + 6x - 3 + 4x + 14 = 180 ← collect like terms on left side
15x + 15 = 180 ( subtract 15 from both sides )
15x = 165 ( divide both sides by 15 )
x = 11
C. a fraction is the same as dividing
Answer:
C. 6,000 km
Step-by-step explanation:
v = speed at S-wave travel through the earth = 8 km/sec
t = time of travel for the S-wave through the earth = 13 minutes = 13 x 60 seconds = 780 seconds (Since 1 minute = 60 seconds)
d = distance traveled by S-wave in the given time interval
Distance traveled by S-wave in the given time interval is given as
d = v t
inserting the above values in the formula
d = (8 km/sec) (780 sec)
d = 6240 km
the closest choice is 6000 km at option C
So Option C
